Optical systems and methods of data reading with collection systems having improved depth of field. One configuration is directed to an image-based optical reading system with a plurality of sensor arrays, such as a charge coupled device (CCD) arranged in a compact configuration to minimize the overall package size while providing extended read range. In an example configuration, two CCD arrays are placed back to back to minimize height and overall package size with fold mirrors providing the optical path to a backward facing array.
